your truck ??
It looks like a '68 Kaiser-Jeep but double check the frame too.
There are two possible areas for the VIN on the left front frame area.
Just behind the steering gearbox and near the upper shock mount.
and the stamping should be about the center of the frame.
I highly recommend using paint stripper to gain access to the numbers.
I started to use a wire brush and damage the numbers ever so slightly.
There may be several layers of paint so it may take a while but keep going.
A wire tooth brush will help with the paint stripper.
You may also find a "Frame Heat Treat Date" near the VIN. That is when the frame was completed and since they did not sit long, would be really close the truck build date by a week or two.
I cleaned the stripped paint up reapplied everywhere except right over the numbers, and then shot 3 coats of clear enamel over the actual numbers in case I need to refer to it again or prove the VIN during the initial police check.
